SPECIFICATION forming part of Letters Patent No. 417,176, dated December 10, 1889..

Application led May 1l, 1889. Serial No. 310,373. (No model.)

.T all 1.071.0111/ it 71mg/ concern/x Be it known that I, ROBERT I). llAINEs, a citizen of the United States, residing` at Cornin g, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Glass-Molds; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it apporta-ins to make and use the same.

My invention relates to improvements in glass-molds; and the object ot' my improvement is to provide a glass-mold having the outside shell made of any suitable material, and a removable lining' for the cavity of same of a different and finer material. I attain this object by a certain combination and arrangement, fully described in this specicat-ion, and illustrated in the accompanying drawings, in which- Figure l is a sectional view of the mold with the lining. Fig. 2 is a similar view without. the lining. mold in an upright centeringl machine, clamped, showing` how the templets are placed in the outer shell with a View of casting,` the lining. Fig. 4 is a sectional view showing,` the templets in the outer half of the mold. Fig. 5 is a transverse sectional view of same. Fig. G is a perspective of one of the templets. l

A designates the body ot the mold, which is made of any suitable material. In each half of the body A there are two screws a, for the purpose of securing` the insideliningB in its normal position. This is accomplished simply by tightening` said screws, as shown in Fig. l. Then itis necessary to remove the lining B. the screws Clare loosened until their inner ends cease to press against said lining. I attach special importance to this feature of my invention, for the reasons hereinafter set forth.

After the outside shell of my mold is constructed I place the same in an upright ccntering-machine, as shownin Fig. Two (2) Fig. 3 is a view of thetemplets, of the size, shape, and style of the mold desired to be manufactured, are then taken and thoroughly smoked, after which they are inserted in the cavity ot' the mold, which is iirmly clamped together by means of said machine. The metal that forms the removable lining B is then prepared and cast into the space between the templets b and the inner cavity of the mold. The mold is then unclamped and the templets quickly removed, leaving a smooth and removable lining. Said lining' may be run of Babbitt metal, or any other metal that is fusible at a low temperature and less of a conductor than iron, which will act in harmony with the glass while being blown and make a clear seamless article.

It will be observed that my mold nray be made of any desired shape or pattern to manufacture tumblers, bottles, lamp-chimneys, dec.

I attach special importance to this invention for the following reasons, namely:

First, the inside lining can be removed at any time and other shapes run into the cavity of the mold. This is easily accomplished and enables a different mold to be made in an hour or so, whereas two or three days would be required by the ordinary method.

Second, by the aid of my invention old molds can be utilized simply by running in a ROBERT D. HAINES. Witnesses:
